The new mom reportedly filed paperwork to trademark the name "Aneres." That's Serena spelled backwards. TMZ reports Serena has the name trademarked for her clothing line and wants the same on a line of beauty products.

On a side note, Serena plays her sister Venus tonight in Indian Wells at the BNP Paribas Open, the 20th match-up between the Williams sisters. The match will air live at 10 p.m. on the Tennis Channel.
